abstract = {The invention relates to a method for enhancing mass spectrometric detection repetitiveness by eliminating dessert effect, belonging to the technical field of detection. Under the weak hydrophobic actions, since polymethyl methacrylate can adsorb some hydrophobic proteins and polypeptides, a polymethyl-methacrylate-site-modified hydrophobic silicon nanopillar array is utilized to provide uniform absorption sites and is inverted in a stirred detected molecule solution; when the array is taken out, no liquid film can be attached to the surface under the hydrophobic actions of the array so as to prevent the coffee-ring effect, and thus, the molecules are uniformly adsorbed to every nanopillar; and finally, the substrate is dropwisely added, and since the volatilization speed of the solution composed of acetonitrile and trifluoroacetic acid which are volatile solvents is greater than the molecule migration speed to both ends, the substrate can not have the coffee-ring effect even after being dried. In general, the method provided by the invention ensures the uniform distribution of the molecules and substrate, thereby greatly enhancing the detection repetitiveness of the detected molecules.

A metal membrane is applied to the surface of a silicon nanocone array in an evaporation manner, then surface plasma element conduction is carried out, photon energy is accumulated in tip positions, and thus a photon library is formed. As the surface is modified with fluoro-substitution alkyl sulfhydryl, a substrate has a large contact angle and a small rolling angle, then the friction of water droplets on the substrate is very small, analyte molecules of a solution are preferentially concentrated at the tips, and the utilization rate of laser energy can be further increased. Therefore, when the silicon nanocone array covered by the metal membrane modified with the fluoro-substitution alkyl sulfhydryl is used as substrate detection analyte molecules, the laser energy can be sufficiently absorbed and effectively utilized, furthermore the desorption ionization efficiency of the analyte molecules can be improved, and the method is applicable to various types of molecules.
